The H&R Ultra Slug guns have combined the heavy barrel concept of the Ultra Varmint rifle to achieve a level of accuracy previously unheard of in firearms below the 1,000 mark. The Ultra Slug guns incorporates the transfer bar safety system, mated to a heavy action and it is rifled for an extremely heavy barrel wall. This process creates the stiffest possible barrel, limiting barrel whip and shrinking group size. The Hunter model features a laminated thumbhole stock and a rifled barrel. It is covered by the NEF lifetime no fault service plan.
